How to copy production database on AWS RDS(postgresql) to local development database.
  1. Change your database RDS instance security group to allow your machine to access it.
    • Add your ip to the security group to acces the instance via Postgres.
  2. Make a copy of the database using pg_dump
    • $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
    • you will be asked for postgressql password.
    • a dump file(.sql) will be created
  3. Restore that dump file to your local database.
    • but you might need to drop the database and create it first
    • $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>
  • the database is restored

Rendering pages server-side with Express (and Pug)

Terminology

  • View: Also called a "template", a file that contains markup (like HTML) and optionally additional instructions on how to generate snippets of HTML, such as text interpolation, loops, conditionals, includes, and so on.
  • View engine: Also called a "template library" or "templater", ie. a library that implements view functionality, and potentially also a custom language for specifying it (like Pug does).
  • HTML templater: A template library that's designed specifically for generating HTML. It understands document structure and thus can provide useful advanced tools like mixins, as well as more secure output escaping (since it can determine the right escaping approach from the context in which a value is used), but it also means that the templater is not useful for anything other than HTML.
  • String-based templater: A template library that implements templating logic, but that has no understanding of the content it is generating - it simply concatenates together strings, potenti

Deploy and reroute traffic from your purchased domain name to your Rails app on a self-hosted EC2 server utilizing GitHub

Punchlist for Serving your Rails App on an EC2 Instance

Run through this list to setup your EC2 instance and host your rails app. This list makes a few assumptions (make changes as necessary)

  • You have github repo with a rails app pushed to it that we'll just pull down to the new server
  • You're using Rails 5.1

If not, see very bottom for steps to build a quick example app.

Launching EC2 instance

  • Use the basic Linux AMI distro: Amazon Linux AMI 2017.09.0 (HVM), SSD Volume Type - ami-8c1be5f6
  • Select a size: t2.micro is fine for this, unless you need larger for a production app
